At the same time, there has also been growing interest and work to incorporate
new sensing inputs to autonomous navigation algorithms that do not rely on day
light conditions and can be used to operate these algorithms in extreme
locations such as lava tubes that are deprived of external lighting. One of the
sensor technologies being investigated for this purpose are thermal cameras,
which measure thermal radiation from all objects in their field of
view [1]}. These types of cameras allow autonomous agents
to operate in all types of lighting conditions and require no external lighting
source.
